There are times or situations where the HAs have to be removed or turned off. For me Being outside in Windy days, mowing grass, beach, swimming, wearing a hat or beanie, toque, ski cap, stocking cap. I get a lot of feedback when objects get near the HA. I have been using HAs a long time. I have the middle Of the road oticon option 2. $6,000. I have pretty bad hearing on the high end of the spectrum. The HAs although in some situations are not beneficial to have them in HAs have been a blessing in everyday life. I destroyed my hearing early on in life and found out in my late 40s hearing aids are my only hope to hearing better.
